Genes affected

CSF1 (HGNC:2432): (colony stimulating factor 1) The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of macrophages. The active form of the protein is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. The encoded protein may be involved in development of the placenta. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.602 is higher than 0.05.
